Solve x − 5y = 6 for x.?
a) x = −5y + 6
b)x = −5y − 6
c) x = 5y + 6
d) x = 5y −6

C.

Step-by-step explanation:

To solve for x you have to move the -5y to the other side of the equals sign.  Since the opposite of subtracting is adding, we will add 5y to both sides to get

x = 5y + 6

Choice C

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
